Renal cell carcinoma (RCC) is the most common malignant tumor involving the kidney. Determining the subtypes of renal cell carcinoma is among the major goals of preoperative radiological work-up. Among all modalities, magnetic resonance imaging (MRI) has several advantages, such as inherent soft tissue contrast, detection of lipid and blood products, and excellent sensitivity to detect small am...

Renal oncocytomas (RO) are the small renal lesions that shared similar histological features with chromophobe renal cell carcinoma (chRCC). There are some hybrid tumors, renal oncocytosis and Brit-Hogg-Dube (BHD) syndrome that have shown the coexistence of both ROs and chRCCs. Presently, most of sporadic cases of ROs and chRCCs have been reported. The majority of ROs and chRCCs patients are asy...

The prognosis for renal metastatic carcinoma is poor: in fact only a small portion of patients have metastases surgically treatable for their number and sizes with often a multiorgan involvement. We present a case in whit a solitary liver metastasis was incidentaly detected 17 years after nephrectomy for renal clear cell carcinoma. during a staging computed tomography performed for colonic canc...

BACKGROUND Acquired cystic kidney disease (ACKD) is a widely known renal cell carcinoma risk factor. DESIGN, SETTING, PARTICIPANTS, AND MEASUREMENTS An ultrasound screening of the native kidneys in all renal transplant patients of a renal outpatient clinic who received a transplant between 1970 and 1998 and presented between 1997 and 2003 (n = 916) was initiated prospectively. A total of 561 ...

Classification The major morphological classifications (WHO/ AFIP; modified Mainz classification, and the Heidelberg classification) discriminate eight sub-types of renal cell tumors related to the basic cell types of the nephron from which they are derived, and in line with the genetic facts as presently understood: 1) metanephric adenoma and metanephric adenofibroma, 2) papillary adenoma, 3) ...

PURPOSE MicroRNAs (miRNA) are a class of small noncoding RNA molecules that have been implicated in a wide variety of basic cellular functions through posttranscriptional regulations on their target genes. Compelling evidence has shown that miRNAs are involved in cancer initiation and progression. We hypothesized that genetic variations of the miRNA machinery genes could be associated with the ...

background and objective: cutaneous cytology is the study of scraping or smears obtained from skin lesions. although not commonly employed, cutaneous cytology has been a useful tool for clinicians due to simplified procedures and high sensitivity and specificity of presurgical clinical diagnosis of common types of skin tumors. this investigation was conducted to study usefulness of cutaneous cy...

intraosseous squamous cell carcinoma is a rare type of squamous cell carcinoma that requires accurate and early diagnose which is important due to its invasive feature. this article presents a rare case report on intraosseous carcinoma in a 33-year-old patient. the case was a 33-year-old man who was referred to oral disease department of babol college of dentistry complaining of chin pain. in t...

Background : Cystic renal cell carcinoma has been reported to have a good prognosis. However, previous studies included cases of multilocular cystic renal cell carcinoma, which has an excellent prognosis, and renal cell carcinoma with cystic necrosis, which has an adverse prognosis. Therefore, we analyzed the prognostic influence of cystic change in clear cell renal cell carcinoma after excludi...
